2 Claims.

This invention relates to improvements in snowguards, being particularlydirected to a construction thereof as applied to roofs of smalldwellings.

Up to the present time, snowguards have been applied mainly to slateroofs of large buildings of the institutional type, and in suchstructures the base of the snowguard essentially was of the shape andsize of an individual slate taking the place thereof in the roofassembly. With respect to installation of a snowguard upon alreadycompleted roofs, considerable difiiculty has been entailed due to thenecessity of removal of slates in order to insert the snowguard of theaforementioned type. With respect to roofs of small private dwellings,it has been impossible to apply snowguards, mainly because of their sizeand weight, also because of their expense. To obviate thesedifiiculties, I have provided a simple constructional formation of asnowguard capable of application to small dwellings and having a baseformation and adjustable guard assembly, whereby the same may be appliedto the roofs of small dwellings, whether upon old roofs or newconstructions.

Broadly, it is an object of this invention to provide for a snowguardconstruction, wherein the base thereof has one portion resting on aslate or shingle and the remaining length thereof is readily slidableunder a plurality of slates or shingles in the adjacent banks or rows ofslates or shingles, the base extension being provided with apertures fornailing the same to the roof, such apertures being so located and spacedas to permit fastening thereof all along its length.

Specifically, it is an object of this invention to provide for asnowguard construction wherein the base thereof is formed of material ofa thickness not greater than one-half the thickness of slates orshingles and normally of not greater than one-half the width thereof,whereby to minimize spacing between the slate or shingle and roof and atthe same time eliminate the tendency of the slates or shingles to crack.

These and other advantages, capabilities and features of the inventionwill appear from the subjoined detailed description of one specificembodiment thereof illustrated in the accompanying drawing, in whichFigure 1 is a side elevation of the device.

Figure 2 is a perspective view of the device.

Figure 3 is a side elevation of a modified form of the device.

Referring to the reference characters in the drawing, there is shown asnowguard unit com- 1935, Serial No. 28,623

prised of a T-shaped cast metal bracket l0 having an upstanding bodyportion H and integral arms I? forming a fiat base. Ihe body portion isU shaped having upstanding ears l3 and I 4 in which ears there areformed apertures i5 and 16 respectively. Associated with ear i3 is oneend of an adjustable carrier bracket I! having an eye 58a disposedadjacent the aperture l5 of the body portion N, there being adapted tobe passed through the aperture of the body and the eye of the carrierbracket pipe P forming one of the guard bars of the device, the carrierbracket being permitted by such formation to be angularly displaced withrespect to ear 13 of the body portion II.

There is associated with the ear M of the body portion an adjustablelatch element 19, the same having an eye 20a. disposed adjacent theaperture of the ear I4, whereby the latch may, at such point, be mountedto the ear [4 by means of nut and bolt assembly 2 I. The latch hasseveral apertures 20b, 20c, and 20d therein which are adapted to beassociated with aperture Zla intermediate of the carrier bar, so that abolt and nut assembly 22 passing through the aperture of the carrier barand one of the apertures of the latch will serve to determine theangular position of the support bar with respect to the bracket. At thefree end of the carrier bar is formed an eye I8b through which isadapted to pass a pipe or guide rod P; the respective pipes or guiderods P and P serving to maintain snow properly on the roof.

As shown in Figure 3, the latch bar indicated in the preferred form ofthe invention, is eliminated and the support bracket is a T-shapedcasting having a body portion of V-notch configuration. An aperture |5ais provided to cooperate with the eye l8 of the carrier bar, wherebypipe P may be passed therethrough. Centrally of the carrier bar isformed an elongated slot 23 through which passes a bolt 24 of a bolt andnut assembly; on the support bracket adjacent the apex thereof and toone side are formed a series of spaced apertures 20', so that the bolt24 disposed in the slot 23 of the carrier bar, when passed through oneof such slots, will form a firm two-point support for the carrier bar onthe support bracket. The free end of the carrier bar has an aperture I8"therein, through which passes pipe PI for the purpose above described.

The support bracket $5 is riveted as at 25' to elongated base 25, theportion 26 of the base directly attached to the arms I2 and !2 of thesupport bracket being provided with a cushion element 26, formed of astrip of lead or like material in a manner and for the purpose asdescribed in applicants Patent No. 1,925,263, September 5, 1933. Theelongated base is of a width no more than one-half of the slate orshingle upon which it is carried and is of a thickness of not more thanone-half the thickness of the slate or shingle, so as to minimize thespacing of the slate or shingle under which the base is carried withrespect to the roof and at the same time to eliminate the tendency ofthe slate or shingle to crack or break.

As will be noted, the base 25 carries a support bracket I9 at one end26, but is sufficiently long as to extend for at least a plurality ofrows of shingles or slates, the elongated portion 21 of the relativelythin base having provided therein separate series of spaced apertures 28and 29, the portion of the base carrying the support bracket beingadapted to rest directly on one slate or shingle, the elongated portionof the base being adapted in the construction of new roofs, to restunder the next succeeding banks or rows of slates or shingles, the basebeing fastened to the roof by passing nails through the aperture series28 or 25 thereof and the adjacent banks or rows of slates or shinglesbeing disposed thereover.

With respect to an old roof upon which the snowguard is adapted to beapplied, a series of snowguards with the pipes P and P removed aredisposed on the edge row of slates or shingles, and the elongated partof the bases thereof passed under the next succeeding banks or rows ofslates or shingles, the snowguard being placed so that some of theapertures in the elongated portion of its base are in line with thejoint between shingles or slates of the adjacent banks or rows ofshingles or slates, thus permitting the base to be nailed to the roofsupport upon which the slates or shingles rest. In order to preventleakage, particularly where the elongation of the base of the snowguardpasses under and between slates or shingles, a bibb 30, shown in dottedlines in Figure 2, is inserted under the slate joint above the base,thus to prevent water leakage.

It is obvious that various changes and modifications may be made to thedetails of construc tion Without departing from the general spirit ofthe invention as set forth in the appended claims.

I claim:

1. In a snowguard, a base disposed on a shingle or slate, a supportcarried thereon, a bracket apertured at one end, a guard bar passingthrough said bracket aperture and said support to form a pivot for thebracket on said support, an aperture at the free end of said bracket forcarrying a second guard, a longitudinal slot intermediate of the ends ofsaid bracket, a plurality of spaced apertures at varying levels formedon each support and means passing through the longitudinal slot of saidbracket and one of the apertures on said support for disposing thebracket at varying angles with respect to said support.

2. In a snowguard assembly, a base disposed on a shingle or slate, saidbase being of relatively thin material and narrow width, a supportcarried thereon, a bracket apertured at one end, a guard bar passingthrough said bracket aperture and said support to form a pivot for thebracket on said support, an aperture at the free end of said bracket forcarrying a second guard, a longitudinal slot intermediate of the ends ofsaid bracket, a plurality of spaced apertures at varying levels formedon each support and means passing through the longitudinal slot of saidbracket and one of the apertures on said support for disposing thebracket at varying angles with respect to said support, and an integralelongation of said base disposed under the adjacent banks of shinglesand slates for firmly supporting the snowguard with respect to the roof.
